Nevermind, the transparent Q, found that in the doc CD. I am curious though
with VTP and VTP pruning enabled, it claims to prune the traffic off the
trunks that do not need the RSPAN traffic, but it does not seem to prune the
vlan itself when I tested it.
I am still curious how to test in the lab, being that there will be no
receiving device on the destination port.
